A team of researchers in Belgium has found that people exposed to orange light exhibit greater brain activity than those exposed to blue light. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they studied brain activity in volunteers undergoing fMRI scanning while different colored lights were shined into their eyes and how it showed that orange light might have an impact on the circadian rhythm.

The research team was studying melanopsin—a light sensitive pigment in photoreceptor cells. Prior research has suggested that the amount of melanopsin present has an impact on the circadian rhythm of certain animals, possibly including humans. To learn more, the researchers sought out volunteers to undergo fMRI scans as lights were shined in their eyes. The idea was to find out if different light colors impacted melanopsin differently.

Each of 16 volunteers was treated to a ten minute shot of blue or orang light as their brains were being scanned. During the test, the volunteers were asked to perform a memory test, to engage the brain.
